Do you have any tests planned using the Sony A7R II with this lens?

DIGLLOYD: a heavy DSLR lens hanging off an adapter is not something I’d want to subject the lens mount on my Sony A7R II to, plus I know of no *good* solutions for Nikon E lenses (if any even exist). Plus it would be awkward and very front heavy. I don't see it as an appropriate mating. Rumor has it that Sony is introducing a 135mm lens soon, and the Zeiss Batis is smaller and lighter and native mount.
